"These strains have been in existence for many, many years," David Noble is president of In Good Health.

"We have states out west that are far ahead of us, we utilized research from those states. Each strain we have provides a different type of relief a different type of physcotropic feeling and we've done research to find the best strains in the marketplace geared to patient's ailments," Noble said.

In Good Health is the only facility in Massachusetts that will grow, process and dispense from the same building. It takes 110 days for marijuana to go from seed to shelf. The Brockton industrial facility has the plants under specially designed LED grow lights with temperature, humidity, air flow and nutrients all carefully controlled.

By the end of the year, it's likely 30 people will work at the facility.

It will not be open to the public. You need a prescription with state identification to allow you through the front door and the screening process.

They have a display room that will show the dozens of strains of marijuana available for purchase as well as food products like brownies, cookies and chocolate. There will be other products like marijuana oil and pastes that can be used in cooking.

It has taken years to get the green plants that grow to six feet tall into production.

"We understood this was going to be a long process, it was challenging because there were so many moving parts we had to satisfy to keep moving. Patients in Massachusetts have been waiting a long time, we feel for them, we are very excited to open and we can't wait to make a difference in people's lives," Noble said.

Once it opens later this summer, In Good Health will be open seven days a week, Monday through Friday from 8 a.m. to 7 p.m. and Saturday and Sunday from 10 a.m. to 4 p.m.
